Ultralow-EMI, 96W, Step-Down ВµModule RegulatorвЂ”
EN55022 Class B Certified in a 15mm x 15mm Footprint
Richard Ying and Willie Chan Designers of information technology and communications systems have come
face-to-face with the difficult challenge of producing feature-rich, power-hungry
products that comply with international EMI standards. Prior to sale, all information
technology equipment (ITE)вЂ”commonly defined as having a regulated clock
signal greater than 9kHzвЂ”must meet government standards such as FCC Part
15 Subpart B in the United States, and EN55022 in the European Union. Both
standards define maximum allowable radiated emission for industrial and commercial
environments (Class A) and home environments (Class B) as shown in Figure 1.
EMI RADIATION SOURCES Electromagnetic waves radiate from any
switching converter and its interface leads.
Pulsating voltages and currents associated
with the switching action of all switch
mode converters from ideal sources generate and directly influence the strength
of radiated electromagnetic waves.
Furthermore, parasitic devices within the Electromagnetic Theory and EMI Switch Mode Regulators
A short reflection on electromagnetic theory can help
one understand the EMI implications of high current,
high power DC/DC step-down converters. switching cycle. MaxwellвЂ™s equations tell us that a
constantly varying electric field creates a selfsustaining electromagnetic wave. GaussвЂ™ law states that the strength of an electric
field in a given area over an enclosed volume is
proportional to the total charge inside it. If currents change rapidly, as is the case in a switch …
